WATCH.

Application med February 7, 191s.

To all 'whom t may concern:

Be it known that I, VILLIAM W'. JORDAN, a citizen of the UnitedA States, residing at Mena, in the county of Polk and State of Arkansas, have invented .certain new and useful Improvements in Vatches, of which the following is a specification, reference being had to the accompanying drawings.

An object of the invention is to provide a case which will effectually exclude dirt and moisture from the watch movement.

Another object is to protect the movement `from injury when the watch is dropped.

A further Object is to provide a case in which crystals of different size may be used.

Other objects and advantages of the invention will be set forth in the ensuing description.

The accompanying drawings show one embodiment of the invention in practical form.

Figure 1 is a plan view of the improved watch. Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1. Fig. 3 is a reproduction of the left-hand end of Fig.' 2 on larger scale, but with certain hinged lids in open position and certain bezels screwed up .farther to clamp smaller crystals. Fig. 4 is a fragmental sectional View on the same scale as Fig. 3 and on the line 4 4 of Fig. 1, but showing a certain slidable bar withdrawn for setting the movement. Fig. 5 is a fragmental perspective view of an elastic packing used between the movement and the case, showing also vthe slidable bar which appears in Fig. 4.

The shading on the cross-section surfaces in the drawings is done with lcloud effect in order to avoid confusion of lines.

Referring to the several figures, in all of which like characters of reference designate like parts, the movement or Works shown in this particular instance includes the usual back plate 10; the front plate 11; the posts 12 connecting said plates; and the dia-l plate 13 which rests on the plate 11. For purposes of this specification, however, the dial plate 13 may be taken as the front plate of the movement.

The improved case shown includes an annular main b ody14 in which the movementI fits, this body having the usual pendant neck 15.

In carrying out the objects stated, an an- Specication of Letters Patent.

serial No. 76,693.

nular cushion or packing ring 16, best shown in Fig. 5, is interposed between the edges of the movement and the inner surface of the annular body 14 of the case, this ring being of cork, rubber, papier mch, or any material having suitable cushion and gasket properties and tensile strength enough not to be crushed out of place by the'shock or compression liable to be brought upon it.

In Letters Patent No. 626,703, issued to me on June 13, 1899, a packing ring is shown and is designated by the numeral 17; said ring 17 resembling the one now'employed, but being in one iece.

In order to slip the ring 17 and its integrally flanged edges 20 and 21 over the edges of a movement, the ring must be of a material which is too elastic to withstand the crushing strain brought upon it by the gripping action of the clamping parts of the case or by dropping the watch. To overcome this defect, my present ring 16 has an integral inward flange at one edge; but the flange 19 at its opposite edge is separable and is put in place after the ring has been slipped onto the edges of the movement.

The ring 16 is preferably made just thick enough in a radial direction to be slightly under compression strain between the edges of the movement and the inner surface of the body 14; this arrangement holding the movement against undue shifting in the case and protecting it against shock when the watch is dropped on its edge.

Where the winding stem 22 of the watch enters the case and passes through the packing ring 16, the inner surface of the main body 14 of the case is recessed around said stem, as at 23, and the outer surface of said packing ring has a proturbance 24 formed on it which is compressed within said recess; this arrangement providing a stuffingbox which prevents passage of dirt and moisture through said ring past said winding stem. A

The setting-lever or setting-bar 25 which projects from the movements of modern watches to an accessible position at the edge of the case, passes out through a notch 26 in the edge of the packing ring 16 on which 105 the separable flange 1,9 is employed, and when said notch must be of considerable depth to allow said setting-bar to pass under the dial plate 13 said flange 19 is pro vided with a depending integral extension 110 respectively, are screwthreaded to said nipples.

Each of the bezels 32 and 33 has an' inwardly-extending elastic flange 34 adapted to rest on the beveled edge 35 of a crystal 3G, and when the bezels are screwed up said flanges act as springs to hold the crystals seated on the yieldable flanges 18 and 19 of the packing ring 16 with an air-tight fit.

Fig. 2 shows the crystals 36 of large size,

but in using smaller crystals, as in Fig. 3,

it is only necessary to screw the bezels 32 and 33 up a little farther to have their spring flanges 34 meet and clamp the beveled edges 31 of said crystals.

ln the use of crystals 36 of smaller diameter, as shown in Fig. 3, the bezels 32 and 33 may be screwed tightly against theupper and lower faces 28 and 30; but in using larger crystals, as in Fig. 2, a gap 37 is left between said bezels and faces. To conceal this gap 37 and provide a finish for the edge of the case, doors or lids 38 and 39 may be provided; and in an open-face case the upper door may bel merely a ring fitting down snugly around the bezel 32.

The doors 38 and 39 may be hinged and may snap down over the usual undercut shoulder 40 onto a downset outward continuation 4:1 of the faces 28 and 30 of the body 14. l

Having thus described the invention, ll claim:

1. rllhe combination with the annular body of a Watch case and a lever set watch movement, of an elastic packing ring interposed between the movement and the body of the case, said packing ring being divided longitudinally into two independent sections adapted to be assembled from opposite sides of the movement, and a ,notch being provided at the joint between the sections for the reception of the setting lever, and means for holding the sections of the packing ring in position. I

2. The combination with the annular body of a watch case and a watch movement, the said body being provided with a winding rstem and having a depression in its inner surface around the winding stem, of an elastic packing ring surrounding the movement so as to be interposed between the same and the body of the case, the packing ring being formed with an opening to receive the winding stem and being provided on its outer surface with an integral protuberance surrounding the said opening and adapted to be forced into the before mentioned depression .of the body to form a stuffing box around the winding stem.

The combination with the annular body of a watch case and a lever set watch movement, said body having a winding stein and being provided with a depression on its inner surface around said stem, an elastic packing ring surrounding the movement and interposed between the same and the annular body of the case, said packing ring being divided longitudinally into two 1ndependent sections adapted to be assembled from opposite sides of the movement and having a notch at the joint between the sections to receive the settinglever, said packing ring being also formed with an opening to receive the winding stem and an integral proturbance surrounding the opening and arranged to be forced into the depression of the body to form a stuiling box around the winding stem, and means for holding the two sections of the packing ring in position.

Witness my hand this 3rd day ofl February, 1916.
